Bring back the shortened date and time format in Windows 11

Since Microsoft has abandoning the ship, here’s a manual way to retain the shortened date and time format.

Okay, before we start, make sure we have a backup of the old format.

Backup

Use the following commands to retrieve the current values of sShortTime and sShortDate:

For sShortTime:

reg query "HKCU\Control Panel\International" /v sShortTime

For sShortDate:

reg query "HKCU\Control Panel\International" /v sShortDate

Show the Shortened Time and Date Command

Enter the following command in PowerShell/CMD as an administrator:

 reg add "HKCU\Control Panel\International" /v sShortTime /t REG_SZ /d "hh:mm" /f
 reg add "HKCU\Control Panel\International" /v sShortDate /t REG_SZ /d "d/MM" /f

To restore back to Defaults

 reg add "HKCU\Control Panel\International" /v sShortTime /t REG_SZ /d "h:mm tt" /f
 reg add "HKCU\Control Panel\International" /v sShortDate /t REG_SZ /d "d/M/yyyy" /f

This time and date format is for Malaysian Standard Time (MST). Yours might be a little different, so change accordingly.
